of printing-machines commonly known `as traveling-cylinder web-printing presses;

and the objects of my inventionvare to pro.-` vide a shorter and more direct path of travel for the web through the machine, to decrease the strain upon the web due to the action of the reciprocating impression-cylinders, and

to provide an improved inking mechanism` for distributing the ink and inking the forms upon the form-beds. y

To these ends myinvention consistsofthe parts andcombinationsof parts,as hereinafter described, and more particularly pointed out in the claims at the end of this specification.`

In the accompanying iive sheets of"dr`aW-' ings, Figure lis a plan viewr of a printing-"machine constructed according to my invention. Fig. 2 is a side elevation ofthe same, and Figs. 3, 4, and 5 are diagrammatic sectional views showing the parts of the machine'in different relative positions., Y

Referring to the drawings and in detail, A and B designate traveling impression-cylinders which are carried by frames or carriages E, which travel upon and are guided upon suitable Ways formed upon side frames 10 of the press, the impression-cylinders coperat-` ing withform-beds C and D, respectively.

A Web-roll W is journaled in bearings in` the side frames 10 at one end of the press,`

and from the Web-roll W the web is fed into the press by the .feedingin rollers 11, 12, and

13, passes up over a looping-in roller 14,1.

down and around a guide roller 15,' from which 1 roller 15 the web passes directly over the fOrmbed C without-bei'nglooped around guide-rollers carried by the impression-cylinder carriage and Without being carried around part of the impression-cylinder, as presses of this character have been heretofore ordinal rily constructed,.but extends directly to the 1 web-roller 16 at the opposite end of the press.

Fromthe web-roller 16 the web passes up and around a .roller 17, which is adjustably mounted in the framework and may serve as a register-roll, `and the web is then led directly over the second form-bed D without passing around any part of the second impression-cylinder or around guide-rollers carried by the impression-cylinder carriage, as this class of presses have heretofore been Ordinarily constructed, but extends directly to a'guideroller 18, up over a guide-roller 19, under and around the looping-out roller 20, between the feeding-ont rollers 21, 22, and 23, from Whichthe web may be fed out of the press to any approved form of cutting or folding device. By threading the web through Ithe press in this manner it will be seen that I'have provided a very1 direct'path of travel for the web through the press, and as the web is not carried around anyportion of the peripheries of the impression-cylinders the web will not be placed under a strain as the cylinders are reciprocated.

The guide-rollers 15 and lrand 17 and 18 are mounted in stationary frames-that is, they are stationary rollers Vwhich have no movement except rotation on their axes. These rollers will stretch the web over the beds parallel therewith or parallel with the Atravel of the cylinders.

The Web-feeding devices, as `before described and as ordinarily employed, are intermittent in their action and serve to hold the web stationary during the taking of an impression and to respace the same over thc `form-.beds to bring the Web intoposition for Web-feeding devices to shift the web through the press and to enable my improved inking apparatus to properly ink the ltype. This means for raising and lowering the bed or beds will thus constitute means for lseparating the web from the form or forms, so that as the web-shifting device acts to respace the web the same will move clear of the form and will not be blurred thereby. While the preferred way of carrying this function out is to raise and lower the beds, of course this function may be carried out by other arrangements or instrumentalities without departing from the scope of my invention as expressed in the claims.

The gearing for driving the press may be arranged in any of the improved or ordinary ways, and, as shown in the drawings, 27 designates a power-shaft to which power may be applied by any of the ordinary means and secured to the power-shaft 27 are gears 26, which mesh with and engage driving-gears 24, journaled upon a shaft 25, provided with eounterweights 241 and connected by wristpins and pitmen 240 to properly reciprocate and drive the im pression-cylinder carriages E back and forth. The gears 26 on their lower sides also mesh with and drive gears 28, carried by a cam-shaft 29, upon which I provide suitable cams 33 and 38for actuating the iutermittent web-shifting devices and for raising and lowering the form-beds to allow the web-shifting devices time to operate.

The web-shifting cams 33 engage with and operate upon rollers 34, carried by the levers 35, which are journaled on studs 36, and at their opposite ends are connected to frames or bars 37, in which the looping-in roller 14 and the looping-out roller 20 are journaled, these parts being moved in an opposite direction by means of'springs 370, as most clearly shown in Fig. 2.

The cams 38 for raising and lowering the type-beds engage and operate upon rollers 39, journaled in slotted. yokes or frames 40, which are mounted upon and Aguided by the shaft 29, the yokes 40 at their opposite ends being connected to knuckle or toggle joints formed by levers 41 and 42, which are suitably pivoted together,thelevers 42 beingjournaled upon the shaft 426 and the levers 41 being journaled upon studs secured in lugs 450 of the framework G. At the opposite end of the framework G similar knuckle or toggle joints,formed by levers 44 and 45,suitably connected together, the lever 45 being journaled upon the shaft 451 and the lever 44 being connected to the llugs 450 of the frames G, are connected with and are operated in unison withthe first set of toggle-joints by means of the pitmen 43. It will thus be seen that the cams 38 operate upon rollers 39 and that the connections last described will raise the formbeds, these parts being moved in an opposite directionby means of springs 400, as most clearly shown in Fig. 2. The toggles are preferably so set that the center thereof will be slightly to the left when the beds are in their raised positions, and suitable stops may be employed to limit this movement to the left, as is common in toggle mechanism, so that the pressure of the cylinders will be strongly resisted.

The frames G are provided with lugs r, which rest upon and engage the adjustable stops 46 and 47, which are mounted on the cross-beams 460 and 470, which connect the side frames 10 of the press.

The inking apparatus which I preferably employ may be arranged and operated as follows: Secured upon the cam-shaft 29 are suitable gears 30, which mesh with and drive gears 31, fastened upon a shaft 32, which carries suitable cams 50 for actuating the inking devices. The cams 50 engage and operate upon rollers 51 and 52, pivoted upon slotted yokes 53, mounted upon and guided by the shaft 32, as shown. The yokes 53 are connected at their outer ends to sectors 54, pivoted upon studs 55 and engaging gears 56, fastened on a shaft 560. Secured upon the shaft 560 are suitable gears 57, which mesh with and engage racks carried by the -reciprocating frames 577 of the upper inking mechanism and which also mesh with and engage racks carried by the reciprocating frames 570 of the lower inking mechanism. In the reciprocating frames 570 and 577 are journaled three pairs of inking-rollers F F, the middle pair being adapted to run onto each of t-he inking-tables to get its supply of ink and to ink the forms placed upon the beds and the two end pairs being arranged to take ink from the fountains and lay or spread the same upon the inking-tables. Ink-fountains K of ordinary construction are located at each end of each bed in position so that the distributing-rollers will carry ink from the same to the inking-tables L.

The feeding-in and feeding-out rollers may be driven by any of the ordinary or approved forms ofgearing, and, as shown in the drawings, oue of the gears 31 meshes with and drives a. gear 101 by means of the intermediate gear 100. The gear 101 has a bevel-gear 102 secured thereto, which meshes with and drives a bevel-gear 104, secured upon a vertical shaft 103, mounted in brackets on the side frame l0. The feeding-in rollers are driven from the vertical shaft 103 by means of the ordinary bevel-gears and intermeshing pinions 120, 110, and 130, and the feeding-out rollers may also be driven from the vertical shaft 103 by any ordinary arrangement of bevel-gears and intermeshing pinions 230, 240, and 210, as shown.

The operation of a press thus constructed `may be easily understood from an inspection of the diagrammatic views shown in Figs. 3,

4, and 5 and may be briefly described as follows: From the web-rollvW the web is constantly fed into the press by means of the feeding-in rollers, and the web is constantly delivered from the press by means of the feed- ICO IIO

ing-out rollers, the web being intermittently held stationary and shifted by the loopingrollers, a's shown. While the web is held stationary the impression-cylinders move over the form-beds in one direction, making an impression upon both sides of the web. The form-beds are then dropped to their lowest position by means of the connections heretofore described. The web is shifted to allow for the succeedingimpression. The forms are reinked by the reciprocating inking-rollers, the inking-rollers traveling over the upper form-bed in an opposite direction from those which travel over the lower form-bed. The form-beds are then raised to their highest position and the impression-cylinders traveled over the forms in an opposite direction to make the succeeding impression upon the web.

I am aware that many changes may be made in the construction of the press by those who are skilled in the art without departing from the scope of my invention, and I do not wish,

therefore, to be limited to the exact construction which I have shown and described; but

What I do claim, and desire to secure by Letters Patent of the United States, is-

1. In a web-printing press, the combination of a form-bed, a traveling impression-cylinder coacting therewith on both forward and backward strokes, a guide at each side of the bed, the web passing directly from one guide to the other, means for positively separating the web from the forms when the cylinder` passes off the forms and vreverses in either direction, and ashifting mechanism for shifting the web when the same is separated from the forms, substantially as described.

2. In a web-printing press, the combination of a form-bed, a traveling impression-cylinder cooperating therewith on both forward and backward strokes, a guide at each side of the bed, the web passing directly from one guide to the other, means for positively separating the web from the forms when the impression-cylinder reverses off the forms in either direction, a shifting mechanism for shifting the web when the same is separated from the forms, and an inking device for inking the forms when the web is separated therefrom, substantially as described.

3. The combination in a web-perfecting printing-press of two form-beds, a traveling impression-cylinder coacting with each of said form-beds, web-'guides arranged at each side of said form-beds so that the web can be led by said guides directly over the form-beds, a suitable web-shifting mechanism and means for separating the web and forms while the shifting action takes place, substantially as described.

Ll. In a web-printing machine, the combination of a traveling impression-cylinder, a form -bed coacting therewith, stationary guides for the web, one at each side of the form-bed, the web being led directly from one guide to the other, means for moving the form bed away from the path of the web, and a suitable web-shifting mechanism, substantially as described.
